In a new interview, his Allied costar Marion Cotillard admitted that filming a sex scene with the A-list actor wasn't as easy and carefree as it may seem.

"We rehearse and had a very determined choreography, and then it allows you freedom. When you know exactly what your body will do, then you can act and you can be free to give the emotions and give the feelings because you won’t think, ‘What am I going to do next? Am I going to go on top of him?’ It’s an awkward situation,” she told reporters during an LA press conference on Sunday, Nov. 13, according to Us Weekly.

“We laughed because you need to get it out because this is so weird. And so you get this time of looking at each other and saying, ‘OK, this is so weird.’ And then we go into this and then I’m going on top of you and then we are going to kiss," the 41-year-old actress explained.

“He had this commitment to do the best he could, which was really, really impressive, so I helped him by being very tough,” she said of their intimate movie scene together. “I was very honest with him. But at the same time, I really wanted to support him in this process that I went through, and I know how hard it is.”

Following Brad's highly-publicized divorce from Angelina Jolie, Marion was rumored to be having an affair with the father-of-six before revealing that she's pregnant with boyfriend Guillaume Canet's child. Now that's awkward!
